Ubuntu has by far the most robust support community. I tried it for a while
in 2007, was a pain. Now I use it with no problem on my cheap Acer laptop
for everything at home other than Adobe stuff. The install image even gave
me an option to resize and partition the Win 7 installation that came with
the laptop was on, easy peasy.
